How can I get my D3 to stop importing all of my FB friends?

Hello all, D3/Android newb here.
My contact list is filled with 250 FB friends, which would be great, but they're all non-editable. I can't add phone numbers to any of them.
Last time, I deleted them all, except for the contacts I want on this phone. After the last sync, they're all back again.
I use the Android FB app, but I don't want this phone to suck in every single friend I have into my contact list. Does anyone know what I'm doing wrong?
